The ON AIR Wrist Watch, designed by Turkey designer Iskender Asanaliev, only has one hand, the hour hand. Additionally the hour hand also indicates the minutes in numbers.

I love both concept and ultra-slick design of the watch.
Another novelty of the watch is how to set the time: push the button for 5 seconds and the LED will start flashing. Now you push upper and/or lower corner to set time.
